Geometrically based statistical channel model for macrocellular mobile environments

We develop a statistical geometric propagation model for a macrocell mobile environment that provides the statistics of angle-of-arrival of the multipath components. This channel model assumes that each multipath component of the propagating signal undergoes only one bounce traveling from the transmitter to the receiver and that scattering objects are located uniformly within a circle around the mobile. This geometrically based single bounce macrocell (GBSBM) channel model provides three important parameters that characterize a channel: the power of the multipath components, the time-of-arrival (TOA) of the components, and the angle-of-arrival (AOA) of the components. Doppler spectra and fading envelopes obtained using the GBSBM model is compared with Clarke´s (1968) model. The results show that the rate of fading at the base station is lower than at the mobile and the reduction in the Doppler spread at the station is dependent on the direction of motion of the mobile with respect to the base station and the radius of the scattering circle
